The Hair Clipper
In Greece male students had their heads shaved with manual hair clippers from the early 20th century until it was legally stopped in 1982. The same practice was implemented in the military, where recruits had their heads shaved as they set foot in the boot camp. In the 1950s and 1960s a law was used in Greece whereby head shaving with manual clippers was to be used as a punishment for young people caught by police. This practice was extended to Greek hippies and leftist youths during the 1967-73 military regime. Obligatory hair clipping was legally stopped in Greece in 1982.
Manual hair clippers are implemented extensively by barbers in India to give short back and sides haircuts.
In early 1921 Mathew Andis, Sr. built a working model of an electric clipper that withstood an extensive range of performance tests. Manufacturing of these new clippers started in the basement of his home, with help from Anna, Mathew's wife. Mathew sold the electric clippers door to door to barbershops in Racine, Wisconsin and the encompassing area. A year later, he founded the Andis Clipper Company. Today, Andis Company remains a family-held business, and constructs hand-held tools to trim, cut, curl, straighten and dry hair. In 1928 the John Oster Manufacturing Company entered the electric clipper market and turned into an industry standard in the USA. Many other businesses make electric clippers, including very cheap unbranded units usually made in China.
There is a range of electric hair clippers from bargain consumer models, sometimes sold with accessories such as clipper guides for adjusting the length of the cut, to clippers for hair-care professionals. The quality difference between the consumer grade and professional grade electric clippers has shortened significantly over the years. The primary difference between the two grades is usually added thermal insulation to stop the unit from heating too much during the prolonged use of professional operation. Professional models may have more durable metal parts in place of some plastic parts in home-use models.
